Sodium chloride is a thickener that is used in the manufacture of shampoos. Salt is not harmful, but if the hair is damaged, excess salt could dehydrate it. Salt is not counterproductive for dyed hair; however, if it can affect the result of a Braziliss treatment, for this, we recommend the use of the complete LISS CONTROL SALON IN line. It should be taken into account that these hairs require treatment, conditioning and proper handling of dryers and irons, with this the hair will maintain its health.
